Looks interesting. Copied and pasted...
The collected plastic waste goes through the stages to be reborn as hydrogen energy. First, in the “preprocessing” stage, impurities like metal, sand, paper are removed, producing plastic waste raw material. Second, with Hyundai Engineering's self-developed “melting” process, the preprocessed plastic waste is heated and stirred to be melted into a viscous liquid state. This process further removes fine impurities. In the gasification process, plastic waste is melted into liquid and introduced into the gasifier alongside oxygen and steam to produce a synthesis gas consisting of CO and H2 using Shell's technology. Lastly, in the synthesis gas refining process, additional H2 is produced through the conversion process of CO, impurities contained in the synthesis gas are removed, and CO2 is separated. This results in the production of high-purity hydrogen from plastic waste, completing the transformation into circular energy.
Don't we have a patent application going in South Korea?
